<aside> 👉 What is PRE?
While the blockchain revolution unlocks the power of decentralized apps, without proper architecture, Web3 platforms built on public blockchains present significant risks to user privacy. The Threshold Network, through its use of threshold cryptography, provides a unique solution to the challenges of user privacy for Web3 platforms.
Threshold’s Proxy Re-Encryption service, PRE, is cryptographic middleware for developing privacy-preserving applications. Proxy Re-encryption is a scalable end-to-end encryption protocol that allows a proxy entity to transform (or re-encrypt) encrypted data from one encryption key to another without revealing the plaintext data. The nodes on the Threshold Network act as these proxy entities and use threshold cryptography to securely and cooperatively re-encrypt data for recipients based on access conditions defined by the data owner.
Thanks to the unique design of Threshold Proxy Re-Encryption, web3 applications can ensure that a user’s data is under the user’s ultimate control while operating on a public blockchain.
